Solar power can save US lives and money

Sunshine can save lives and American dollars too. US scientists have just worked out how many lives, and at what price, solar power can deliver.

LONDON, 19 June, 2017 – US scientists know how to save lives, make money and make America great again. The answer? Switch from coal to solar power. This would save up to 52,000 lives, and deliver electricity at the same time.

True, it would cost $1.45 trillion to deliver the photovoltaics to fully replace all 755 gigawatts of America’s coal-powered electricity. Right now, solar panels deliver only 22.7 gigawatts of US electricity.

But over the 25-year warranty timespan of the renewable technology, that would work out at a cost of $1.1m per life saved from all the respiratory, cardiovascular, nervous, urinary and digestive mortality linked to coal power generation.

Making a profit

And significantly, $1.1m is comparable to the value assigned to any human life in US economic studies. The researchers say that they arrive at that figure without including the value of the electricity generated by photovoltaics.

Bad bargain

The study comes just weeks after US President Trump vowed to resurrect the US coal industry and to withdraw from the international climate accord signed in Paris in 2015. That committed all signatories to work with other nations to switch from greenhouse gas-emitting technologies to renewable sources of power, to contain global warming to within 2°C by the end of the century.

“If we are rational and we care about American lives – or even just money – then it’s time to end coal in the US”

Importantly, the Michigan Tech scientists focussed only on deaths from air pollution linked to coal-burning power stations: they did not make a calculation about the economic costs of chronic illness linked to polluted air, nor did they estimate the health costs that might be linked to the entire coal industry, nor include the estimates of deaths that might be attributed to climate change as a consequence of prodigal fossil fuel combustion.

According to World Health Organisation estimates, around 7 million people die worldwide each year from air pollution: any reduction in coal-burning could save lives beyond America’s shores.

“Solar has come down radically in cost, it’s technically viable, and coupled with natural gas plants, other renewables and storage, we have ways to produce all the electricity we need, period”, Professor Pearce said.

“My overall take-away from this study is that if we are rational and we care about American lives – or even just money – then it’s time to end coal in the US.” – Climate News Network
